PHOSPHORUS-CONTAINING MOLECULAR SIEVE, ITS PRODUCTION AND USE Russian patent published in 2022 - IPC B01J29/82 B01J35/10 B01J37/02 C01B39/02 C10G47/10 

FIELD: chemistry.

SUBSTANCE: inventions relate to phosphorus-containing molecular sieves, their production and use. A phosphorus-containing molecular sieve having a faujasite structure is described for use in hydrocracking of initial hydrocarbon materials, having a phosphorus content per oxide from 0.3 wt.% to 5 wt.%, a pore volume from 0.2 ml/g to 0.95 ml/g, and the ratio of the content of Brensted acid centers and the content of Lewis acid centers from 3.4 to 9.5, while the molecular sieve has a structural spectrum of NMR ²⁷Al, which is a ratio of I₆₀ w.f./I_-1 w.f., which is from 5 to 40, and the ratio of L_-1 w.f./I_±6 w.f., which is from 0.4 to 2. A method for the production of the above-described molecular sieve is described. A hydrocracking catalyst including the above-described phosphorus-containing molecular sieve, and its production method are described.

EFFECT: increase in the activity of a hydrocracking catalyst.
